Simulative Analysis with QRED to Decrease Packet Loss

Abstract

Communication networks are facing packet loss at routers, where different approaches are used to reduce. Similarly RED is one of them, that existing RED [1] [2] algorithm and its variants are found in flow controlling. For minimizing dropping of packets and reducing buffer overflow. This paper propose a new routing algorithm in which additional FIFO controlled queue buffer before existing RED algorithm, to increases performance and throughput of the router. It is experimented and improvements in results are shown with help of OMNet++.
